Renesas unveils first mcus from RH850/F1x line up

Designed for automotive body applications, the devices are available with on chip 40nm flash memory from 256KB up to 8MB. Various package options are available and dual-core versions are also planned. The RH850/F1x series is made up of three groups from low to high end. All the groups share the same cpu core architecture and the same selection of peripheral functions to allow common software to be used for different system units. The devices have been optimised to offer low power consumption (0.5mA/MHz for the RH850/F1L) and higher reliability. All products incorporate power supply shutoff circuit technology for reduced current consumption. Additional new functions for security and diagnosis include an 'intelligent' cryptographic unit for data encryption; diagnostic functions that provide support for the ISO 26262 standard; and an increased number of channels that support monitoring for changes in digital or analogue input signals in low power mode without the need to activate the cpu. Development tools provided by Renesas for the RH850/F1x series include the Renesas eclipse embedded studio, e2studio and the E1 on chip debugging emulator. There are also plans to provide support for software conforming to the Automotive Open System Architecture (AUTOSAR) standard.
